3 Changes between versions 0.4b44 and 0.4b45 (released ?????????????)
4 ===================================================================
6 1. Improve data throughput when using compression in dump by
7 allowing multiple slaves to compress in parallel. Thanks
8 to Phillip Susi <psusi@cfl.rr.com> for the patch.
10 2. Add dump encryption support and reorganise the whole
11 compression/encryption code as plugins. Thanks to
12 Bear Giles <bgiles@coyotesong.com> for the patch.
14 Changes between versions 0.4b43 and 0.4b44 (released June 10, 2011)
15 ===================================================================
17 1. Recognize ext4 partitions in dump -w commands (Sourceforge
18 bug #3125587, RedHat bug #658890). Thanks to Jan Görig
19 <jgorig@users.sourceforge.net> for reporting the bug and
22 2. Fix an issue with multi volume backups, which breaks
23 restoring of files which are splitted on two or more
24 volumes and are starting on 2nd tape or later (RedHat
27 3. Fix a bug in dump when dumping files with holes. This bug
28 was introduced in 0.4b42 while adding ext4 support.
29 (Sourceforge bug #3133762).
31 4. Fix a bug in restore -P where useless index files for compressed
32 dumps were created (Debian bug #583093). Thanks to
33 Mark Wooding <mdw@distorted.org.uk> for the patch.
35 5. Fix SYS_clone invocation on s390 architectures (Sourceforge
36 bug #3303235). Thanks to Adam Tkac <atkac@redhat.com> for
39 6. Fix static builds. Thanks to Peter Volkov <pva@gentoo.org>
42 7. Fix false negatives in configure zlib test. Thanks to
43 Bear Giles <bgiles@coyotesong.com> for the patch.
45 8. Add quick regression script from Bear Giles <bgiles@coyotesong.com>.
47 9. Fix a bug introduced in 0.4b43 causing restore to crash when
48 asking for a new volume when doing multi-volume restores. Thanks
49 to Patrik Schindler <poc@pocnet.net> for reporting the bug.
51 Changes between versions 0.4b42 and 0.4b43 (released June 11, 2010)
52 ===================================================================
54 1. Fix a bug in dump making impossible to handle large toc files
55 (> 2 GB). Thanks to X DUGi <xdugi@users.sourceforge.net> for
56 reporting the bug (Sourceforge bug #2820629)
58 2. Fix 'restore -x' in multi-volume mode, which caused files being
59 spanned on the first and second volumes to be incorrectly extracted.
60 Thanks to Adam Tkac <atkac@redhat.com> for reporting the bug.
61 (there may be several bug reports about this issue, including
62 Sourceforge bug #2117008, RedHat bugs #232415 and #444958).
64 3. Remove -lselinux -lsepol from the standard libraries list,
65 they shouldn't be needed if selinux is not enabled in dump
66 (this also fixes a build failure when selinux libraries are
69 4. Fix restoration of extended attributes of fifos and device nodes.
70 Thanks to Igor Zhbanov <izh1979@gmail.com> for the bug report.
72 5. Don't attempt to set extended attributes on files that were not
73 extracted in 'restore -N' mode. Thanks to Jan Görig
74 <jgorig@users.sourceforge.net> for the patch.
76 6. Make the dump man page explicit about ext4 support.
78 7. Fix a bug in dump which caused EA entries to be unrecognizable by
79 restore in some corner cases. Add a workaround to restore making
80 it able to properly deal with those corrupted EA entries. Thanks
81 to John Austin <jaustin1@users.sourceforge.net> for reporting
84 8. Fix some issues when restoring a dump which was generated using
85 exclusion patterns (either via -e or via the nodump attribute)
86 (see the Debian bug #574667 for details. Thanks to Frédéric
87 Brière <fbriere@fbriere.net> for the bug report and the associated
90 9. Fix progress/estimated blocks display in dump when doing really
91 huge backups. Thanks to Steve Bonds <sbonds@users.sourceforge.net>
92 for the bug report and tests. (Sourceforge bug #2987758)
94 10. Improve level 1 dump speed by rearanging the "mapdirs" code.
95 Thanks to Andreas Kies <andikies@t-online.de> for finding the
96 bottleneck and sending a patch (Sourceforge bug #2998119).
98 11. Use only ctime in order to compare newness instead of both
99 ctime and mtime. This should both speed up dumping time and
100 correct some side-effect bugs (like dumping files with an mtime
101 in the future in every incremental backup). Thanks to
102 Kieran Clancy <codebeard@users.sourceforge.net> for reporting the
103 bug (Sourceforge bug #2999207).
105 12. Extract dumped UNIX sockets instead of ignoring them.
106 (Sourceforge bug #3007216).
108 13. Compiler warning fixes (mainly warn_unused_result ones).
110 Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009)
111 ===================================================================
113 1. Fix printout of the 'Connection to' message in dump/restore.
114 Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
115 bug report and its fix.
117 2. Fix dump -w/-W output for filesystems having the last backup
118 level equal to 0. Thanks to Pascal Bouchareine
119 <kalou@users.sourceforge.net> for reporting the bug.
121 3. Enable restore to handle restoring onto a different SELinux
122 policy from the dump. Thanks to Tony Nelson
123 <tony_nelson@users.sourceforge.net> for the patch.
124 (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845
127 4. Fix EA set failures when restoring immutable files. Thanks
128 to Andrew Kroeger for the patch.
130 5. Fix "mode file too large" errors when restoring huge backups.
131 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
134 6. Add the ability to link against libtinfo library if present,
135 instead of libtermcap or libncurses libraries. Thanks to
136 Adam Tkac <atkac@redhat.com> for the patch.
138 7. When comparing a backup, do not consider to be an error the fact
139 that we encounter files created while dump was in progress.
140 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
143 8. Force '-a' to be the default value when running 'restore -C'.
144 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
147 9. Many improvements to the 'cron_dump_to_disk' example.
148 Thanks to Aaron S. Hawley <ashawley@users.sourceforge.net> for
151 10. Fix the QFA generation when extended attributes are backuped
152 along with the inodes. Prior to this fix, the entries for
153 some inodes may get corrupted (duplicated entries or incorrect
154 ones), making the QFA file unusable for repositionning in
155 restore. Many thanks to Kenneth Porter <shiva@sewingwitch.com>
156 for the bug report and the testing of the fix.
158 11. Fix EA restoration in debug mode (Sourceforge bug #1986216).
160 12. Stefan Auracher <star7@onlinehome.de> noticed that the Tower
161 of Hanoi backup strategy documented in the man page wasn't
162 actually based on the Tower of Hanoi algorithm. The man page
163 was updated accordingly.
165 13. Fix missing level information from dump output when using
166 the default level (RedHat bug #493635). Thanks to Adam Tkac
167 <atkac@redhat.com> for the patch.
169 14. Fix the dump man page to reflect the fact that the default
170 dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac
171 <atkac@redhat.com> for the patch.
173 15. Fixed a few spelling errors in the man pages (RedHat bug #489853).
174 Thanks to Adam Tkac <atkac@redhat.com> for the patch.
176 16. Fixed restore man page and program usage which incorrectly stated
177 that -P and -A were both allowed in the same invocation (RedHat
178 bug #490627). Thanks to Adam Tkac <atkac@redhat.com> for the patch.
180 17. Use sys_clone under Linux to share I/O contexts between dump
181 processes, thus drastically increasing the performance of dump
182 under CFQ (which is the default I/O scheduler used in a number of
183 distributions). Thanks to Jeff Moyer <jmoyer@redhat.com> for the
186 18. Add (preliminary) ext4 support - thanks to libext2fs which does
187 all the job for us. Thanks to Gertjan van Wingerde
188 <gwingerde@gmail.com> for the patch.
190 Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
191 =====================================================================
193 1. Fix restore of dumped Access Control Lists. The previous
194 code for EA works fine, but ACLs needed conversion from the
195 ext2/3 disk format to posix_acl format before restoring.
197 2. Fix some issues with restoration of EA on big endian
200 3. Fix restore when the symtab is over 2GB in size.
202 4. Made the directory hash indexing an optional feature,
203 accessible by the '-H' option of restore, and disable it
206 5. Fixed dump to not include extended attributes information
207 in the toc (archive) file which confused restore -t.
209 Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
210 =================================================================
212 1. Changed restore to emit warnings (instead of emitting a fatal
213 error) if a file (or a directory) is unavailable for a
214 comparision (if the user doesn't have the necessary permissions
215 to access it for example). Thanks to Kenneth Porter
216 <shiva@sewingwitch.com> for the bug report.
218 2. Re-done the 'do not save directory entries to non-dumped inodes
219 (excluded from dump)' feature. The previous implementation
220 worked well for excluded directories but not for regular files.
221 Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
224 3. Fixed a bug in dump where the tape size was miscalculated when
225 the user used -d/-s to specify the tape characteristics. Thanks
226 to Philip Goisman <goisman@physics.arizona.edu> for reporting
229 4. Fixed another bug introduced in restore with the hashtree
230 implementation. This one caused restore to stop saying
231 "removenode: non-empty directory" in some cases.
233 5. Added support for dumping and restoring ext2/3 extended
234 attributes (EA), like the access control lists (ACL) or
235 the security labels used by SELinux.
237 Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
238 ======================================================================
240 1. The newly added dump_on_cd_3 example was buggy, replace it
241 with an updated version from Andrew Basterfield
242 <bob@cemetery.homeunix.org>.
244 2. Made restore to chdir() back into the initial directory when
245 dumping core while aborting a comparision operation. The
246 previous behaviour was to write the corefile at the root of
247 the directory being compared, which could very well be
248 read only and preventing the corefile generation. Thanks
249 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
251 3. Silenced the failure to call fgetflags() when comparing an
252 entry which has no ext2 attributes (as in lsattr()).
254 4. Fix a brown paper bug in restore -C which broke restore and
255 caused modifications on the filesystem being compared
256 (directories containing a file with the same name as the
257 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
258 <shiva@sewingwitch.com> for finding the bug and helping me
261 5. Made restore -C force the -N flag (no writing allowed on
262 the disk) in order to prevent more bugs like the above one.
264 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
265 =====================================================================
267 1. Fix a couple of troff syntax bugs in the man pages.
268 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
270 2. Made restore use either libncurses or libtermcap, depending
271 on which one is available at configure time.
273 3. Fixed restore negative size display bug when comparing a
274 dump containing files over 2GB. Thanks to Steve Bonds
275 <sbonds@users.sourceforge.net> for the bug report.
277 4. Do not save directory entries to non-dumped inodes
278 (excluded from dump). This will eliminate the 'missing
279 file' warnings when doing 'restore -C'.
281 5. Fix dump crash when backuping a huge (2TB) filesystem,
282 due to a bogus calculation on the inode map size.
283 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
284 submitting the bug and testing the fix.
286 6. Fix a problem in restore where the final \0 in the symbolic
287 link names could have been lost, generating corrupt filenames.
288 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
291 7. Implemented a hash list for the directory names in restore.
292 The linear list used before caused problems in interactive
293 restores when dealing with directories having thousands of
294 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
295 for reporting the bug.
297 8. Improved restore -C, this time including the directory
298 attributes into the comparision.
300 9. Made restore understand tapes containing EA/ACLs (which will
301 be dumped by the next version of dump). In this version
302 extended attributes on the tape are ignored, for full EA/ACL
303 support wait for the next version or try the experimental EA
306 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
307 ==================================================================
309 1. Added the --enable-staticz configure option which enables
310 dump and restore to be linked with static versions of
311 libz and libbz2 (and dynamic versions of all other libraries).
312 This will make Debian users happy, because libz and libbz2
313 were the only needed libraries living in /usr, all the
314 others live in /lib. In case of system emergency, it is
315 better not to have to rely on an extra filesystem.
316 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
318 2. Fix compilation on (at least the Linux Debian port to) AMD64.
319 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
320 that are also defined by <linux/types.h> (<asm/types.h>) and
323 3. Make dump's reading of the dumpdates file a bit more robust,
324 preventing dump from crashing when the dumpdates file has
325 been modified by hand.
327 4. Fixed some offset calculations in dump code which could
328 lead to "bread lseek errors" on large filesystems. Thanks
329 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
330 reporting this bug and debugging the issue.
332 5. Made dump use the blkid library when searching for devices
333 by label or uuid instead of dump's own routines.
335 6. Corrected a bug in dump where a wrong LABEL=... line in
336 /etc/fstab could prevent dump from dumping unrelated
337 filesystems. Thanks to Bruce Lowekamp
338 <lowekamp@users.sourceforge.net> for reporting the bug.
340 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
341 ====================================================================
343 1. Fixed dump compilation with old gcc versions. Thanks to
344 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
346 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
347 when compiling against a recent glibc version.
349 3. Fixed a bug in restore preventing the read of a dump tape
350 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
351 <phiggins@transzap.com> for reporting the bug and providing
354 4. Changed dump to enable the creation of volumes of different
355 sizes in a single run (make -B accept a list of values).
356 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
358 5. Use the glibc provided minor() and major() macros instead
359 of our own bitmask implementation. This should be safe for
360 when the major/minor namespace will migrate to 32 bits.
361 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
364 6. Made explicit in the dump man page that dump will not create
365 a remote file, it will only write to an already existing one.
367 7. Another try at making size estimates better again.
369 8. Put back the inconditional running of the end-of-tape
370 script which was changed in 0.434 to be run only when -M
371 or multiple -f were NOT specified. Some users rely on this
372 feature even when it is combined with -M/-f.
374 9. Fixed restore when restoring huge backups (where rstdir...
375 temporary files are over 2GB). Thanks to
376 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
377 debugging the issue and making the patch.
379 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
380 David <vrtin@users.sourceforge.net> for submitting the bug
381 and providing a test case.
383 11. Made dump work with an arbitrary integer level (no more 10
384 levels only limitation). Thanks to Matthew
385 <msvincen@midway.uchicago.edu> for the patch.
387 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
388 =======================================================================
390 1. Added a note in the dump man page saying that the default
391 blocksize can be 32 if -d is used with a high density argument.
392 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
395 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
396 LDFLAGS environment variables. Thanks to Arcady Genkin
397 <antipode@users.sourceforge.net> for reporting the bug.
399 3. Made -e/-E options of dump accept an unlimited number of inodes
400 to be excluded, rather than a hardcoded maximum. Thanks to
401 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
403 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
404 and -D_USE_BSD_SIGNAL defines in configure in order to solve
405 64bit build problems because quad_t is redifined with a
406 different signature. Thanks to Mike Harris <mharris@redhat.com>
407 for reporting this bug.
409 5. Made restore build on Solaris, making possible to
410 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
411 <uwe@ugsoft.de> for the patch.
413 6. Made an extension in the dump tape format capable of saving
414 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
415 wrote the extension and contributed the restore code back
416 into this codebase. The same extension mechanism will be
417 used in the future to save ACLs...
419 7. Made rmt work correctly with regard to QFA and local/remote
420 files and tapes. The remote access will however work only
421 when the dump provided rmt version is used. If you want to
422 use another rmt server, please do not use the QFA feature.
423 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
425 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
426 ====================================================================
428 1. Fixed the INSTALL file to reflect the actual install paths.
429 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
432 2. Fixed the configure script to only check for headers presence
433 instead of trying to compile them. This should fix issues
434 with old build environments. Thanks to Kari Lempiainen
435 <kari@funky.pp.fi> for reporting the bug.
437 3. Fixed restore to correctly ignore sockets when comparing
438 a dump (as socket cannot be properly restored anyway). Thanks
439 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
441 4. Fixed restore to correctly access the archive file (-A argument)
442 even when using a remote tape. Thanks to Fabrice Bellet
443 <fabrice@bellet.info> for reporting the bug.
445 5. Fixed (again) handling of long (largefile) seeks in rmt.
446 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
449 6. Fixed restore corner case when dealing with large block sizes
450 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
451 <fabrice@bellet.info> for reporting the bug.
453 7. Fixed a bug preventing dump to access a filesystem having
454 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
455 for reporting the bug.
457 8. Made dump store dump dates using explicit timezones, fixing a
458 problem with incremental dumps if the timezone is modified
459 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
460 the bug report and the patch.
462 9. Fixed a bug encountered when dumping individual files (not full
463 filesystems or directories) and dangling symbolic links happen
464 to be in the list of files. For as far as dump is concerned,
465 dangling symbolic links are allowed, and are dumped as is.
466 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
467 bug and providing the fix.
469 10. Fixed open and creation modes and permissions for QFA and
470 table-of-contents files in dump and restore. Thanks to
471 Philippe Troin <phil@fifi.org> for the patch.
473 11. Fixed the archive file descriptor handling enabling it to be 0.
474 This can happen in some cases when shell redirections are used.
475 Thanks to Philippe Troin <phil@fifi.org> for the patch.
477 12. Delayed the opening of archive file until after suid had been
478 dropped (fixing a possible security issue if dump is suid).
479 Thanks to Philippe Troin <phil@fifi.org> for the patch.
481 13. Fixed the 'S' command handling in the rmt client part.
482 Thanks to Philippe Troin <phil@fifi.org> for the patch.
484 14. Modified the end-of-tape script handling to print out statistics
485 (and stop the timer) before launching the eot script. Also, the eot
486 script does not get run anymore when using -M (which makes sense) or
487 when multiple tapes are listed on the command line
488 (-f tape0,tape1,tapen) (which also makes sense).
489 Thanks to Philippe Troin <phil@fifi.org> for the patch.
491 15. Relicensed dump/restore under the 'revised' BSD license, as per
492 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
494 16. Added LZO compression to dump. This new compression method has
495 the advantage of being super fast, thus not killing tape streaming
496 on slow machines. Thanks to Helmut Jarausch
497 <jarausch@igpm.rwth-aachen.de> for the patch and to
498 Markus Oberhumer <markus@oberhumer.com> for giving special permission
499 to include his miniLZO project (GPL licensed) in dump/restore.
501 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
502 <ant@notatla.demon.co.uk> for reporting the bugs.
504 18. Added a special rmt version which can do encryption when writing
505 to tape. Read examples/encrypted_rmt/README for details on
506 how to enable and configure it. Thanks to Ken Lalonde
507 <ken@globalremit.com> for the patch.
509 19. Made dump work with 2.5 kernel end of tape early warning semantics.
510 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
512 20. Fixed a bug which caused dump -w|-W not to work anymore, because
513 the fs_freq and fs_passno fields in /etc/mtab are always set
514 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
517 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
518 =======================================================================
520 1. Added a note in the restore man page clarifying the question
521 'set the permissions on the current directory ?' asked by
522 restore at the end of treatment in -i and -x modes.
524 2. Fixed the endianess issues when reading compressed tapes.
525 Thanks to Dark Force <daq4th@users.sourceforge.net> for
526 reporting this bug and providing test cases.
528 3. Fixed the "ACL won't be dumped" warning message (which showed
529 an extra, unrelated error message). Thanks to Dragan Krnic
530 <dkrnic@lycos.com> for reporting this bug.
532 4. Made dump look first into /etc/mtab, then into /etc/fstab
533 when searching for filesystem paths. Also fixed some problems
534 caused by binding mounts or multiple block device mounts.
535 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
536 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
537 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
538 and #160305, Sourceforge bugs #618699 and #679832).
540 5. Made dump's -I option accept the value '0' meaning all the
541 read errors will be ignored. This can be useful when running
542 dump from unattended sessions (like cron jobs). Thanks to
543 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
545 6. Fixed the output of dump to indicate 'blocks' instead of
546 'tape blocks' in the various messages (blocks are always
547 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
548 made it clearly print the current blocksize at the start of
549 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
552 7. Made rmt understand long (largefiles) seeks.
554 8. Fixed build with very old versions of libext2fs, where
555 EXT2_FT_* constants were undefined.
557 9. Made dump accept the dumpdates path on the command line
558 (-D file option) instead of using only the hardcoded one.
559 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
562 10. Enabled rmt, LFS, readline, QFA options by default in
563 ./configure. Updated the configure process (new versions
564 of config.guess, config.sub etc).
566 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
567 =======================================================================
569 1. Changed dump to use fcntl(F_SETLK) style locking instead
570 of flock() when locking the dumpdates file. With the old
571 locking scheme, a local user having read rights on the
572 dumpdates file could be able to do a Denial of Service attack
573 on dump. In order to lock the dumpdates file with the new
574 scheme, the user would need to have write access on the file.
575 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
576 reporting the bug (originally a bugtraq post).
578 2. Fixed interactive 'ls' which caused spurious errors warnings
579 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
580 <jorgen_ostling@users.sourceforge.net> for reporting this
583 3. Fixed dump's estimate when dealing with sparse inodes.
585 4. Modified dump to allow setting a blocksize bigger than 32kB
586 (raised the limit to 1024kB), because newer hardware needs
587 this for proper operation. Thanks to Dirk Traenapp
588 <dtraenapp@users.sourceforge.net> for reporting this.
590 5. Fixed a bug causing Dump to stop and report an error if an
591 inode number in the exclude file was followed by some amount
592 of whitespace. Thanks to Jeffrey Sofferin
593 <sofferin@users.sourceforge.net> for reporting this bug.
595 6. Fixed a bug which caused restore, in some particular cases,
596 to ask some 'scary' questions and leave a bunch of RSTTMP
597 directories behind when restoring incremental tapes. Thanks
598 to Philippe Troin <phil@fifi.org> for reporting this bug and
599 providing the test cases.
601 7. Changed the wording when inodes are excluded from dump:
602 replaced 'Added inode 7 to exclude list' with
603 'Excluding inode 7 (resize inode) from dump', as suggested
604 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
606 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
607 ===================================================================
609 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
610 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
611 <eros@lamel.bo.cnr.it> for reporting the bug.
613 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
614 ===================================================================
616 1. Made dump print out the ext2 logical block number in case of a read
617 error, which can be given as an argument to debugfs' ncheck command,
618 in order to find out the affected inode. Added note about this
619 usage in dump's man page.
621 2. Fixed a problem in restore when reading tapes written on big
622 endian machines with very old versions of dump. The patch was
623 contributed by George Helffrich <george@geology.bristol.ac.uk>.
625 3. Fixed the tape length calculation when using large tapes
626 and compression. Thanks to Georg Lippold
627 <g_lippold@sourceforge.net> for reporting the bug.
629 4. Added a new set of examples in dump_on_cd_2 directory, based
630 on dump_on_cd examples but somewhat enhanced, supporting DVD
631 media, and localized in english and german. Thanks to
632 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
634 5. Made dump save 32 bit UID/GID. Internally, this was achieved
635 by switching from the old BSD inode format to the new BSD
636 inode format, which means that the tape format was changed.
637 However, since all restore versions out there should
638 transparently support both inode formats, the change should
639 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
642 6. Fixed a lot of warnings in the code shown when compiling
643 with 'gcc -W'. Thanks to Matthias Andree
644 <matthias.andree@stud.uni-dortmund.de> for reporting this.
646 7. Fixed a small markup bug in the dump man page. Thanks to
647 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
650 8. Rewrote entirely the man pages using the tmac.an macro
651 package (Linux man page format) instead of the original BSD
652 format. They should be now cleaner and easier to modify.
654 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
655 ==================================================================
657 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
658 non Linux clients were misinterpreted. The description of the problem
659 (incompatible numbering in Linux mtio opcodes) is documented at
660 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
661 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
662 providing an excellent, cross-platform replacement for rmt in his
665 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
666 which caused restore to fail when the inode maps were not entirely
667 contained on the first volume (when using really small volumes or
668 when dumping a huge number of inodes).
670 3. Fixed a problem in dump, where files in subdirectories of directories
671 that have the nodump flag set (or being excluded with -e/-E) were
672 sometimes incorrectly dumped (instead of being excluded). The original
673 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
674 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
675 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
676 help testing the patch.
678 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
679 which makes one able to pipe the output of dump, by the net, to
680 a remote CD-burner server.
682 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
683 and use GNU's symbolic syntax over rmt instead of numerical values
684 to assure multiple platform compatibility.
686 6. Documented the -d option in restore.
688 7. Added a -v (verbose) mode to dump. For now it just prints the number
689 of the inode being dumped, but this could evolve in future versions
690 to include interesting debugging output.
692 8. Added a -o flag to restore, which automatically restores the current
693 directory permissions in -i or -x mode, without asking the operator
694 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
695 and Peter Samuel <peters@e-smith.com>.
697 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
698 ====================================================================
700 1. Fixed a bug in the QFA feature which could have caused
701 a bad tape positionning on restore (causing extra delays in
702 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
704 2. Added a small note in the dump man page specifying that
705 there should be no white space between the option letter and
706 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
708 3. Made restore work with older versions of the readline library,
709 by checking in configure for several extended symbols. Restore
710 can now be compiled with a readline as old as the 2.0 release
711 (though it may be a good idea to upgrade it to a more recent
712 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
713 reporting the build failures.
715 4. Fixed a performance problem with the QFA file creation in
716 dump, which made unnecessary seeks on the tape slowing down
717 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
718 reporting this issue.
720 5. Removed the inclusion of some kernel headers in the dump
721 source, which prevented the compile in some kernel/glibc
722 headers/architecture combination. Thanks to Bdale Garbee
723 <bdale@gag.com> for reporting the bug.
725 6. Added the appropriate error message when dump fails to
726 open the output file for writing. Thanks to Amith Varghese
727 <amithv@yahoo.com> for reporting this bug.
729 7. Made restore able to understand large Solaris ufsdump tapes
730 (containing inodes bigger than 4194304). Sun have introduced
731 an "extension" to the dump tape format when dealing with
732 those inodes, which was uncorrectly handled by Linux restore.
733 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
734 providing a test case.
736 8. Added the -m parameter to dump which optimises the output for
737 inodes having been changed but not modified since the last dump
738 ('changed' and 'modified' have the meaning defined in stat(2)).
739 For those inodes, dump will save only the metadata, instead of
740 saving the entire inode contents. Inodes which are either
741 directories or have been modified since the last dump are saved
742 in a regular way. Uses of this flag must be consistent, meaning
743 that either every dump in an incremental dump set have the flag,
746 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
747 =======================================================================
749 1. Fixed behaviour of dump when exceeding resource limits
752 2. Added the -L flag to restore to allow the user to specify a
753 maximal allowed number of miscompares when using restore
754 with the -C option to check the backup.
756 3. Detailed the manual entry for the -N option of restore.
758 4. Added the -a flag to restore to make able doing unattended
759 restores in -i or -x mode (automatically walks through the
760 multiple dump volumes).
762 5. Extended the QFA mode to work with local files and/or
763 remote tapes and files. This way, restore can know in advance
764 the tape number and the offset for the inodes to extract and
765 can minimize the extraction time by seeking directly to the
768 6. Added the -A <archive> option to both dump and restore,
769 which makes dump to archive a dump table-of-contents in
770 the specified file to be used by restore to determine
771 whether a file is in the dump file that is being restored.
772 (the archive file syntax is also compatible with the
773 Solaris ufsdump generated one).
775 7. Small fix in restore making it able to read some (broken ?)
776 Solaris ufsdump tapes.
778 8. Fixed dump to correctly recognise the root filesystem when using
779 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
780 for reporting this bug.
782 9. Added the -P <file> option to restore to create a
783 Quick File Access file from an already made dump. Patch
784 contributed by Uwe Gohlke <uwe@ugsoft.de>.
786 10. Made restore compile and run on Solaris, making it a
787 possible replacement for the standard ufsrestore. Port was
788 contributed by Uwe Gohlke <uwe@ugsoft.de>.
790 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
791 =====================================================================
793 1. Added a set of backup scripts from Eugenio Diaz
794 <getnito@yahoo.com> in the examples section. It features
795 automatic (cron based) full and incremental dumping of
796 several filesystems on a separate filesystem.
798 2. Fixed a off-by-one miscalculation which disabled dumping
799 a one letter subdirectory. Thanks to Chris Siebenmann
800 <cks@utcc.utoronto.ca> for reporting the bug.
802 3. Fixed several restore bugs occuring when trying to
803 restore some missing files on the tape. Thanks to Chris
804 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
806 4. Fixed --with-ldopts configure argument passing, installing from
807 a separate object directory, makefile cleanups contributed
808 by <splite@purdue.edu>.
810 5. Fix a bug which could caused, in some conditions, the highest
811 number inode of a filesystem, to not be dumped. Many thanks
812 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
815 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
816 =======================================================================
818 1. Added a mini howto from Patrick Walsh in the examples
821 2. Minor man pages syntax corrections. Thanks to
822 Chris Danis <screechco@home.com> for reporting the bugs.
824 3. Added a script from David B. Peterson <dave@toppledwagon.com>
825 to the examples section. It features dumping several
826 filesystems to a remote tape drive upon ssh.
828 4. Added a patch provided by Richard Jones <rich@annexia.org>
829 which allows BRADEMAX (number of read errors tolerated by
830 dump) to be adjusted using the -I option.
832 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
833 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
836 6. Add the -l option to restore to specify if, when doing a
837 remote restore, the file used to access the backup is a
838 regular file (the defaults being a tape drive). Restore needs
839 to know this information when reading a remote compressed
840 dump. Previously, this information was autodetected, but
841 the autodetection code fails (with ioctl: Inappropriate ioctl
842 for device) when using a non Linux remote box. Thanks to
843 many users and especially to Eros Albertazzi
844 <eros@lamel.bo.cnr.it> for reporting this.
846 7. Found a workaroung for the dump deadlock problem (3 childs
847 stuck in pause(), father in read()). The workaround seems
848 to work for me and several beta-testers. If it doesn't work
849 for you, please report back.
851 8. Updated the RPM spec file (BuildPrereq, URL etc).
853 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
854 ========================================================================
856 1. Fixed the permissions of a newly created QFA file by dump.
858 2. Cleaned up the source of dump (the external variables
859 definition was a complete mess, making possible to have
862 3. Fixed restore to use the full tape volume path when doing
863 a compare (since it changes the working directory to the
864 filesystem being compared in the process).
866 4. Added the -q option to dump which makes dump abort
867 whenever it needs operator attention. It should be
868 easier to use dump in scripts with this option.
870 5. Detect the use of incompatible options to dump and
871 refuse them (like -a and -B options together).
873 6. Added bzip2 compression to dump/restore (use option -j level
874 to select it). Note that you will need a restore version
875 >= 0.4b24 in order to restore a bzip2 compressed dump.
876 The same warning as for the zlib compression applies:
877 the tape format of a bzip2 dump is not compatible with the
878 original BSD tape format.
880 7. Fixed a overflow problem in dump corrupting the dump when
881 very large files were encountered. Thanks to Vladimir Nadvornik
884 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
885 kernel buffer/page cache before starting the dump, helping
886 a bit those who use dump on mounted filesystems. Thanks to
887 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
890 9. Updated the RPM spec file following the RedHat changes
891 (dynamically linked binaries now in /usr/sbin etc).
893 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
894 which enables restore to recognise multi volume compressed dumps
895 done on CD. Included his scripts for dump (which pipe the dump
896 output directly into cdrecord) and restore. There is now
897 possible to to backups to CD on the fly!
899 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
900 ===================================================================
902 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
903 Marcus Meissner (Caldera International Security Dept.).
905 2. Implement the Sun rmt extended protocol. Patch submitted
906 by Ian Gordon <iangordon@users.sourceforge.net>.
908 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
909 the linux kernel header. This ensures that dump always has the
910 latest version of this file. Patch submitted by
911 Andreas Dilger <adilger@turbolinux.com>.
913 4. Report any filesystem present in either /etc/fstab with a
914 positive passno or /etc/dumpdates in dump -w output.
915 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
917 5. Fixed the looping problem in dump introduced in the
920 6. Changed the -B option of dump to limit the size of
921 _compressed_ output per volume if compression is on.
922 Patch contributed by Helmut Jarausch
923 <jarausch@igpm.rwth-aachen.de>. Note however that, since
924 it is impossible to predict the size of the compressed
925 data before doing the compression, the -B limit is a bit
928 7. Fixed a bug in reading the operator typed file/tape path for
929 the next volume in restore.
931 8. Implemented a "-F script" option to restore which permits the
932 user to specify a script which will be launched at the
933 beginning of each tape, useful for automatic programming of
934 tape changers for example. See the restore man page for the
935 script parameters and return codes.
937 9. Small fix for the QFA routines provided by Uwe Gohlke
938 <uwe@ugsoft.de>, and some recommendations for QFA uses in
941 10. Fixed the multivolume restoring where making a mistake
942 to the 'Mount next tape' prompt caused several blocks to
945 11. Enhanced the -e option of dump to take as a parameter a
946 comma separated list of inode numbers.
948 12. Added the -E option to dump which specify a file containing
949 inode numbers to exclude from the dump.
951 13. Fixed the compressed multi-volume dump + restore.
953 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
954 ==================================================================
956 1. Made dump report the number of blocks dumped per volume.
957 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
959 2. Fix a bug in dump where waiting too much at the 'change volumes'
960 question caused the volume to be rewritten. Thanks to
961 Graham Reed <greed@users.sourceforge.net> for reporting the
962 bug and providing a patch.
964 3. Added a compression option to dump, contributed by Jerry
965 Peters <gapeters@worldnet.att.net>.
967 WARNING: the compression works only on files/pipes and
968 drives supporting variable block size.
970 WARNING2: tapes created using the compression feature are
971 incompatible with the standard dump tape format, and a
972 version of restore >= 0.4b22 will be needed for extraction.
974 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
975 architectures. Thanks to Paul Slootman <paul@debian.org> for
976 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
979 5. Many cleanups (CPP defines, const char warnings, check of
980 ext2fs COMPAT flags, time_t cleanups, added libext2 version
981 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
983 6. Made --prefix option work in configure. All the install path
984 are now based on the configure parameters.
986 7. Added the Quick File Access mode in dump/restore, contributed
987 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
988 a file tape position for each inode, and this file is used by
989 restore (if called with parameter Q and the filename)
990 to directly position the tape at the file restore is currently
991 working on. This saves hours when restoring single files from
992 large backups, saves the tapes and the drive's head. Use
993 --enable-qfa option of configure to compile in the QFA support.
995 8. Added the possibility to dump several files and directories
996 in a single invocation of dump. Thanks to Uwe Gohlke
997 <uwe@ugsoft.de> for implementing this option.
999 9. Fixed the dumping and restoring of files with holes
1000 (files ending with holes didn't get dumped or restored
1003 10. Fixed a socket descriptor leak in dump, which leaved opened
1004 3 file descriptors per dump process (and there is one dump
1007 11. Fixed dump large file system support, by explicit use of
1008 open64/lseek64/etc functions (explicit use needed because
1009 e2fsprogs libraries don't behave well when compiled with
1010 FILE_OFFSET_BITS=64).
1012 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
1013 ======================================================================
1015 1. Fixed some bugs in the dump -w|-W logic introduced by
1016 the previous version. Thanks to Andreas Dilger
1017 <adilger@turbolinux.com> for his help on this one.
1019 2. Fixed again a compilation problem when using old e2fs
1020 headers (filesystem label related). Thanks to many users
1021 who reported this stupid error.
1023 3. Fixed a build problem on old lib5 based systems dealing with
1024 _PATH_MNTTAB being undefined. Thanks to John Adams
1025 <johna@onevista.com> for reporting the bug.
1027 4. Improved the error detection in restore when creating
1028 the temporary files in TMPDIR. Now restore will corectly
1029 report a 'no space left on device' error instead of
1030 strange errors which could imply an archive corruption.
1031 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
1032 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
1034 5. Added the throughput information in dump's progression
1035 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
1038 6. Use libext2fs's inode scanning routines, which are particularly
1039 robust when dealing with errors (especially when having some
1040 bad blocks on the filesystem). Many thanks to Colin
1041 <colin@horizon.com> for reporting the bug, investigating
1042 the issues, finding a workaround, writing the patch and
1043 fully testing it... (of course, if this patch will break
1044 anything, he is to blame for :-)).
1046 7. Made dump and restore LFS aware. Dump can dump a filesystem
1047 containing large files, generate a large file on output and
1048 restore can restore them. This feature is not enabled by
1049 default, use --enable-largefile option of configure to enable
1050 it (you need to have a LFS aware glibc though). Thanks to
1051 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
1052 and to Theodore T'so <tytso@valinux.com> for his always
1055 8. Made dump ask upon a tape write error if it should rewrite
1056 the current volume (assume this is a bad tape) or if it should
1057 assume an end-of-tape condition (useful for tape drives which
1058 behaves badly at the end of the tape). Thanks to Andreas
1059 Dilger <adilger@turbolinux.com> for the suggestion.
1061 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
1062 =======================================================================
1064 1. Fixed a small compilation problem due to a change
1065 in the definintion of the struct sigaction in
1066 glibc 2.0 / libc5. Thanks to Gunther Schlegel
1067 <schlegel@riege.de> for reporting the bug and to
1068 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
1071 2. Modified the label and uuid analysis in order to be
1072 self-contained (independant of kernel/libc headers). This
1073 should fix the compile with older kernel/libc headers and
1074 will preserve the functionality. Thanks to Bernhard Erdmann
1075 <bernhard.erdmann@gmx.de> for reporting the bug.
1077 3. The 'exclude inode' option, if applied to a directory
1078 inode, excludes now correctly all the leaves of this
1079 directory. Thanks to John R. Dennison
1080 <gerdesas@users.sourceforge.net> for reporting the bug.
1082 4. Fixed the '-e' option to disable the possibility
1083 to exclude the root inode (which causes the dumps to
1084 be unreadable by restore). Prevented array overflow
1085 when multiple -e options are used.
1087 5. Fixed dump to correctly interpret a filesystem argument
1088 which is a mountpoint and it is not an absolute path
1089 (as specified in the fstab). Thanks to Bernhard R. Erdmann
1090 <be@berdmann.de> for reporting the bug.
1092 6. Made dump able to backup files larger than 2 GB. Note that
1093 dump still doesn't cope with files larger than 4 GB.
1095 7. Restore the real uid and gid before invoking an external
1096 RSH program (big hole when dump or restore is suid root!).
1098 8. Get the values for the default tape device and the location
1099 of fstab file from the system headers. Thanks to
1100 Andreas Dilger <adilger@turbolinux.com> for the patch.
1102 9. Made dump -w|-W report all recognized filesystems
1103 present in either /etc/fstab or /etc/dumpdates, and present
1104 the list in the same order as in fstab file. Thanks
1105 to Andreas Dilger <adilger@turbolinux.com> for the patch.
1107 10. Made dump's -a (automatic end of tape detection) the
1108 default. Specifying one of -B, -c, -d or -s options will
1109 override the EOM detection. Thanks to Andreas Dilger
1110 <adilger@turbolinux.com> for the patch.
1112 11. Save the ext2 filesystem label into the dump volume label.
1113 Specifying a volume label on the command line (-L option)
1114 will override this feature. Thanks to Andreas Dilger
1115 <adilger@turbolinux.com> for the patch.
1117 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
1118 =====================================================================
1120 1. Fixed the signal handling in dump (which I broke in 0.4b17)
1121 which was causing several strange dump failures (dump
1122 hanged or segmentation faults etc).
1124 2. Specified the default blocksize in the dump man page.
1126 3. Changed two info messages of restore to be written on stdout
1127 instead of stderr in order to leave stderr only for errors
1128 or warnings. Thanks to Stephen Atwell
1129 <satwell@urbana.css.mot.com> for the suggestion.
1131 4. Corrected an off by one calculation which prevented
1132 dumping a directory having a 1 character name length.
1133 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
1134 for reporting the bug.
1136 5. Reinforce dump in order to allow only level 0 and no
1137 -u option when dumping a subdirectory, and document
1138 this in the man page. Thanks to Bernhard Erdmann
1139 <bernhard.erdmann@gmx.de> for reporting the bug.
1141 6. Fixed a small harmless bug in restore which caused
1142 in some conditions hard links to be restored several
1143 times (therefore generation some warning messages).
1144 Thanks to Kenneth Porter <shiva@well.com> for
1147 7. Updated the RPM spec file to the latest RedHat version,
1148 providing FHS packaging and other cosmetic changes.
1149 You will need RPM version >= 3.0.5 in order to build the RPM.
1151 8. Updated the configure script to check for libtermcap
1152 before checking for libreadline, because we need this
1153 library in order to compile the readline support.
1155 9. Made dump understand the LABEL= and UUID= notation
1156 both in /etc/fstab and on the command line. Note that
1157 you will need the /proc filesystem in order to use
1158 these notations. Thanks to Erik Troan <ewt@redhat.com>
1159 for providing the patch.
1161 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
1162 ===================================================================
1164 1. Fixed a potential buffer overflow in restore. Thanks
1165 to Stan Bubrouski <satan@fastdial.net> for reporting
1168 2. Fixed a readline-related bug which prevented
1169 'cat DUMPFILE | restore -i -f -' from working. Thanks
1170 to Charles Karney <karney@users.sourceforge.net>
1173 3. Changed a few "panic" into "exit", causing restore to
1174 be more stable against some attacks (like the last one
1175 reported on Bugtraq, although the last version of restore
1176 was not vulnerable - just dumped core). Thanks to
1177 Andreas Hasenack <andreas@conectiva.com.br> for reporting
1180 4. Removed the suid-root bit on dump and restore in the
1181 default build (and generated RPMs). It should be safer
1182 now. Users who need the suid-root capabilities in order
1183 to make network backups should read first the man page
1184 of dump and enable the suid bit manually.
1186 5. Added -ltermcap to the compile parameters for restore
1187 when using readline support, in order to make the compile
1188 process work on some systems (SuSE ?). Thanks to
1189 Patrik Schindler <poc@pocnet.net> for reporting the bug.
1191 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
1192 ====================================================================
1194 1. The -F script is called now *only* at the end of a tape,
1195 not at the end of the dump. Thanks to Christian Haul
1196 <haul@informatik.tu-darmstadt.de> for the bug report.
1198 Normally, the device name and the current volume number
1199 are passed on the command line of the script. However,
1200 if you want the old style script (with no arguments
1201 passed on the command line), you can enable it in
1202 configure with the --enable-oldstylefscript.
1204 2. Use posix signal handling to preserve dump functionality
1205 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
1208 3. Made the exit code of restore in case of a 'C'ompare
1209 command reflect the result of the compare. An exit status
1210 of 0 means the dump archive is correct, 1 means tape errors,
1211 2 means that some files were modified. Thanks to Kenneth Porter
1212 <shiva@well.com> for the suggestion.
1214 4. Made (finally) quotes work in interactive restore.
1216 5. Small fixes in order to allow dump to compile with a
1217 really old e2fsprogs version. Thanks to Ian Zimmerman
1218 <itz@speakeasy.org> for the bug report.
1220 6. Add GNU readline capabilities to interactive restore.
1221 Use configure's --enable-readline flag to enable this feature.
1222 Thanks to Patrik Schindler <poc@pocnet.net> for the
1225 7. Do the compare on the fly in restore 'C' mode (this will
1226 allow not to exhaust the available /tmp space when
1227 ccmparing large files). Thanks to Kenneth Porter
1228 <shiva@well.com> for the suggestion.
1230 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
1231 ====================================================================
1233 1. Fixed some several duplicate 'DUMP: DUMP:' in the
1236 2. Corrected the estimation of blocks to dump. Note that
1237 this is still wrong for large directory inodes, due
1238 to the size of a BSD directory entry on the tape
1239 (estimation is based on the size of the ext2 directory,
1240 which is smaller because it doesn't contain the null
1241 character at the end).
1243 3. Made dump report the total number of MB written to
1244 tape at the end of run. Thanks to W. Reilly Cooley
1245 <wcooley@nakedape.cc> for the patch.
1247 4. Added the -X option to restore giving the possibility
1248 to read the names of the files to be extracted/listed
1249 from a text file (in addition of the command line).
1250 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
1253 5. Added the device name and the current volume number
1254 as arguments to the end of tape script (dump -F option).
1256 6. Made the multi-volume dump work again (after having
1257 broken it in 0.4b15).
1259 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1260 ===================================================================
1262 1. Added a prompt command in interactive restore mode. Thanks
1263 to Andreas Dilger <adilger@home.com> for the patch.
1265 2. Fixed a buffer overflow problem in dump (caused by
1266 not checking the size of the filesystem parameter).
1267 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1268 reporting this on Bugtraq (and to several dump users
1269 who forwarded me his mail).
1271 3. Added the '-F script' option to dump in order to
1272 launch a script at the end of each tape (to be used
1273 with a tape changer, or to notify the sysadmin by
1276 4. Fixed a bug in restore compare code caused by the changes
1279 5. Fixed the treatment of options using the old BSD syntax
1280 in both dump and restore.
1282 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1283 =======================================================================
1285 1. Fixed a bug in dump which may have caused invalid deleted
1286 directories to be dumped out if they were deleted after the
1287 mapping pass. This could occure on active filesystem and lead
1288 to heap corruption (causing dump malfunction in many possible ways).
1289 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1290 bug and submitting the patch.
1292 2. Fixed the handling of the filesystem parameter in dump. A
1293 '/mnt/disk' parameter caused the disk contents to be dumped,
1294 but a '/mnt/disk/' parameter caused the mountpoint directory
1295 to be dumped (generally an empty directory).
1297 3. Improved the output of dump in order to tell which directory
1298 it is currently dumping (when dumping a subtree).
1300 4. Added the '-e' exclude inode option to dump. Thanks to
1301 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1303 5. Added a REPORTING-BUGS file in order to provide a guide
1304 on how to correctly report a bug in dump/restore.
1306 6. Fixed a restore problem when restoring a hard link to an inode
1307 having the immutable or append-only attribute set. Thanks to
1308 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1310 7. Fixed a compatibility problem between dumps made on little
1311 endian machines (the format was correct) and big endian
1312 machines (the format was incorrect). This fix break the
1313 compatibility with the older dumps made on big endian
1314 machines (sparc, m86k, ppc etc). For the first time in
1315 linux dump's history (I believe), the dumps made by *BSD,
1316 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1317 so interchangeable. Thanks to Rob Cermak
1318 <cermak@ahab.rutgers.edu> for submitting the bug and
1319 helping me test the fix.
1321 8. Fixed the way dump reports the remaining percent/time, if
1322 the number of blocks actually dumped exceeds the estimated
1323 number of blocks. Thanks to Jean-Paul van der Jagt
1324 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1326 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1327 ======================================================================
1329 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1330 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1332 2. Removed the requirement to build the RPM as root from the
1333 spec file. Thanks to Christian Weisgerber
1334 <naddy@mips.rhein-neckar.de> for submitting this.
1336 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1337 causing dump to block when dumping really huge filesystems.
1338 Many thanks to Patrik Schindler <poc@pocnet.net> for
1339 helping me find this bug.
1341 4. Fixed the treatment for an interrupt signal when dump access
1342 the remote tape through RSH. Thanks to Christian Weisgerber
1343 <naddy@mips.rhein-neckar.de> for providing the patch.
1345 5. Fixed a bug which was causing dump/restore to display
1346 garbage characters instead of the remote host name.
1348 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1349 =====================================================================
1351 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1352 <kukuk@suse.de> for submitting the patch.
1354 2. Fix for the exit code when using the size estimate option of
1355 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1356 submitting the patch.
1358 3. Handle EINTR in atomical reads/writes in dump, which was causing
1359 dump to fail on some systems. Thanks to Eric Jergensen
1360 <eric@dvns.com> for reporting the bug and submitting the patch.
1362 4. Handle more than 16 characters for the device names in dumpdates.
1363 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1364 tracking down the problem and proposing the solution.
1366 5. Fixed a bug in dump which prevented the creation of the
1367 dumpdates file when doing a 0-level dump without already
1368 having a dumpdates file. Thanks to Patrik Schindler
1369 <poc@pocnet.net> for reporting the bug.
1371 6. Changed the way dump 'S' flag reports the size estimate
1372 from number of blocks into bytes (making it compatible
1373 with the Solaris version, and simplifying things for
1374 amanda users). Thanks to Jason L Tibbitts III
1375 <tibbs@math.uh.edu> for reporting the bug.
1377 7. Fixed a compatibility problem in linux/alpha dump tape format.
1378 Now the linux/alpha dump are (again) compatible with the
1379 other dump formats. But this breaks compatibility with
1380 older dumps made on alpha. Thanks to Mike Tibor
1381 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1383 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1384 ======================================================================
1386 1. Added a '--enable-kerberos' to configure.
1388 2. Added a 'S' option to dump which determines the amount of space
1389 that is needed to perform the dump without actually doing it, similar
1390 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1391 <cermak@ahab.rutgers.edu>.
1393 3. Added a 'M' multi-volume option to dump and restore which enables
1394 dumping to multiple files (useful when dumping to an ext2
1395 partition to make several dump files in order to bypass the 2GB
1396 file size limitation). The 'f' argument is treated as a prefix and
1397 the output files will be named <prefix>001, <prefix>002 etc. With
1398 the 'M' flag, restore automatically selects the right file without
1399 asking to enter a new tape each time.
1401 4. Fixed a memory leak which was causing dump to grow very big
1402 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1403 Fearon <jasonf@netrider.org.au> for reporting the bug.
1405 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1406 ======================================================================
1408 1. Make configure test if the system glob routines support
1409 extended syntax (ALTDIRFUNC). If not, use the internal glob
1410 routines instead of system ones. Thanks to Bernhard Sadlowski
1411 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1412 and helping me resolve this and other minor libc5 compiling
1415 2. Fix a problem when dumping a ext2fs with the 'filetype'
1416 feature enabled. Thanks to Patrick J. LoPresti
1417 <patl@cag.lcs.mit.edu> for reporting the bug and to
1418 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1420 3. Made the nodump flag work on directories. A directory which
1421 has the nodump flag gets never dumped, regardless of its
1424 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1425 which allows dump on an active ext3 filesystem. However, this
1426 is a "quick and dirty" patch which enables backup of an ext3
1427 filesystem through the ext2 compatibility (by ignoring the
1428 NEEDS_RECOVERY bit). The journal file is not recognized and
1429 it is dumped (it should not).
1431 5. Test the superblock compatibility flags when dumping, in order
1432 to be sure that we know how to deal with specific features.
1434 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1435 ====================================================================
1437 1. Use lchown instead of chown, fixing a possible security problem
1438 when restoring symlinks (a malicious user could use this
1439 to deliberately corrupt the ownership of important system files).
1440 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1441 this and providing the patch.
1443 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1444 ====================================================================
1446 1. Put dump sources under CVS, added Id tags in all files so
1447 one can use 'ident' on binary files.
1449 2. Added the dump/restore version in the usage text so one can
1450 easily verify the version he is using.
1452 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1453 a va_start/va_end problem on linux-ppc (always call va_start
1454 va_end in pairs each time we use a vararg function).
1456 4. Added again the DT_* constants because old libc does not
1457 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1458 for submitting the bug report.
1460 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1461 this should enable dumping big (huge) filesystems.
1463 6. Added the RSH environment variable in order to be able to
1464 use a rsh replacement like ssh when doing remote backups (and
1465 bypass the security limitations of rcmd). Now you can do remote
1466 backups without being root (or making dump setuid root).
1468 7. Modified again the way dumpdates works. For incremental dumps,
1469 we need to read dumpdates even if we are not using 'u' option.
1470 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1473 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1474 ===================================================================
1476 1. Removed the 'k' flag from the restore 'about' text if kerberos
1477 was not compiled in.
1479 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1480 to them (fsetflags takes a char*, setflags an open fd!).
1482 3. (f)setflags is called only if the flags aren't empty. If the
1483 file is a special file, a warning is printed, because changing
1484 flags implies opening the device. Normally, a special file
1485 should not have any flag... (Debian bug #29775, patch provided
1486 by Abhijit Dasgupta <abhijit@ans.net>).
1488 4. Made possible to dump a file system not mentioned in /etc/fstab.
1489 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1491 5. Changed the default behaviour to not create dumpdates
1492 unless 'u' option is specified. Removed the old "debian-patch"
1493 which provided the same thing. (Debian bug #38136, #33818).
1495 6. Removed all those dump*announce, since they were getting old...
1497 7. Added warning messages if dumpdates does not exist and
1498 when an inferior level dump does not exist (except for a level 0
1501 8. Debugged the glob calls in interactive mode: restore used a
1502 dirent struct which was different from the /usr/include/dirent.h
1503 one (this used to work, is it a glibc2 change?), so none of the
1504 compat glob (which used /usr/include/dirent.h) or the system glob
1505 worked. Restore use now the system dirent (and the system
1506 DT_* constants), which are compatible with BSD ones.
1508 9. Added a configure flag (--with-dumpdatespath) to specify
1509 the location of dumpdates file. By default, it is
1512 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1513 included the current date/version in man pages.
1515 11. Corrected the estimation of remaining time when
1516 the operator doesn't change the tapes quickly enough. This
1517 was an old bug, I thought I corrected it, and discovered
1518 that in fact it was corrected in two different places, so
1519 the results canceled each other...
1521 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1522 ===================================================================
1524 1. Integrated multiple patches from RedHat, Debian and SuSE:
1526 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1528 - several fixes in the man pages.
1529 - update the default tape device to /dev/st0.
1530 - many updates for Linux Alpha (byte ordering, size_t etc).
1532 - use environment variable for TMPDIR (instead of /tmp).
1533 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1534 - workaround egcs bug (RedHat bugs #4281 and #2989).
1535 - wire $(OPT) throughout Makefile's.
1537 2. Upgrade the dump revision to 1, making possible to dump filesystems
1538 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1540 3. Fix some compile warnings, prototype all functions.
1542 4. Use glibc err/glob instead of internal compatibility
1543 routines (only if available).
1545 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1546 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1548 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1549 ======================================================================
1551 1. Integrated the changes from FreeBSD-3.1-RELEASE
1552 (mostly bug fixes, buffer overruns, dump has now an "automatic
1553 tape length calculation" flag, dump/restore can use kerberos now
1554 (this is NOT tested), use environment variables for TAPE and
1557 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1559 3. Corrected a bug in restore when using 'C' option with multi-volumes
1560 tapes (files splited accros two tapes give "size changed" errors
1563 4. Corrected the long standing bug when dumping multiple tapes.
1564 This works for me, needs further testing.
1566 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1567 ====================================================================
1569 1. Dump now runs correctly on kernels 2.1.x
1570 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1572 Changes between versions 0.4b2 and 0.4b3
1573 ========================================
1575 1. Use realpath() if available
1577 2. Report statistics
1579 Changes between versions 0.4b1 and 0.4b2
1580 ========================================
1582 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1585 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1587 3. Fixed configure.in to correctly handle --enable-rmt
1589 Changes between versions 0.3 and 0.4b1
1590 ======================================
1592 1. Integrated the changes from 4.4BSD-Lite2
1594 2. Integrated the patches from Debian and Red Hat
1596 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1598 4. Changed dump to use the Ext2fs library to get block addresses. This
1599 should solve the endianness problem on SparcLinux.
1601 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1602 distribution's one) to use autoconf
1604 6. Fixed a few minor bugs
1606 Changes between versions 0.2e and 0.2f
1607 ======================================
1609 1. Added the creation of named pipes (fifos) in restore.
1611 2. Added the -N flag in the restore manual page.
1613 3. Added the file kernel.patch which contains the llseek() optimization
1614 patch for 1.2.x kernels.
1616 4. Fixed a bug in the restoration of symbolic links: owner and group were
1619 5. Integrated some changes from FreeBSD 2.2.
1621 6. Added a call to ftruncate() after restoring each file to restore
1622 correctly files ending by a hole.
1624 Changes between versions 0.2d and 0.2e
1625 ======================================
1627 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1628 with owner = root (0) and group = root/wheel/whatever (0).
1630 Changes between versions 0.2c and 0.2d
1631 ======================================
1633 1. Dump is now able to backup 2GB+ filesystems.
1635 2. Dump and restore can now be linked as static binaries.
1637 Changes between versions 0.2b and 0.2c
1638 ======================================
1640 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1642 Changes between versions 0.2a and 0.2b
1643 ======================================
1645 1. Really fixed the bug that I should have corrected in 0.2a.
1647 2. Enabled optimization again.
1649 Changes between versions 0.2 and 0.2a
1650 =====================================
1652 1. Disabled the optimization during compilation.
1654 Changes between versions 0.1 and 0.2
1655 ====================================
1657 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1658 the fs_type field (actually, I modified the file fstab.c to make it
1659 use the mntent functions).
1661 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1662 made by dump should be readable by the BSD restore and backups made
1663 by the BSD dump should be readable by restore. Unfortunately, this
1664 means that the dump format has changed between version 0.1 and version
1667 3. Dump is now able to backup a subtree, it is no longer limited to whole
1668 filesystems like the BSD version.
1670 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1673 Changes between versions 0.0 and 0.1
1674 ====================================
1676 1. Now create links rdump and rrestore during the `make install' step.
1678 2. Linux port specific bugs added to the manual pages
1680 3. Incorrect estimation of the number of tapes blocks fixed when doing
1681 incremental backups.
1683 4. Better ls-like format in restore in interactive mode.
